Abstract

On polymérise des styrènes ou copolymères un mélange de styrènes et d'autres monomères vinyliques en utilisant comme initiateur de polymérisation, un peroxyde organique dont la température de décomposition correspondant à dix heures de demi-vie est de 40 à 70 degrés C, à raison de 1 à 10 % par rapport au poids des styrènes ou au poids total des styrènes et des autres monomères vinyliques, la température de polymérisation étant de 50 à 120 degrés C. On obtient ainsi des polymères de la série des styrènes qui sont incolores et qui présentent une basse masse moléculaire, à l'aide d'un appareil de polymérisation simple et avec un rendement élevé.Styrenes or copolymers are polymerized a mixture of styrenes and other vinyl monomers using, as polymerization initiator, an organic peroxide whose decomposition temperature corresponding to ten hours half-life is 40 to 70 degrees C, at a rate of 1 to 10% relative to the weight of styrenes or to the total weight of styrenes and other vinyl monomers, the polymerization temperature being from 50 to 120 degrees C. Polymers of the styrene series are thus obtained which are colorless and which exhibit low molecular weight, using a simple polymerization apparatus and with a high yield.
